Well my theory has nothing to do with the BF knowing she would be a nun, the book came with her regardless of what she would be. And KFC is suggesting that anything the BF wrote to herself in the final moments would be safe from Regina as Regina wasn’t making many trips to the abbey.
The writers stated that the BF didn’t have her memories during the curse but they didn’t say that she couldn’t access them. I still think that the BF did like Dumbledore and took out her memories and put a note to herself so she could access her memories again
I see where you’re going with this (though it’s important to remember that when Dumbledore took out the memories and put them in the Pensive, he didn’t forget them. It was way for him to actually view and in some cases go to that specific memory. It didn’t delete them from his head). As for the BF…maybe? I have always maintained that her final preparations we heard about in The Stranger had something to do with the book and making sure it ended up in her hands. I suppose she could also have done something like Rumple did to ensure that she would remember when Emma came to town, though her interaction with Emma was limited in S1 so I don’t know what would trigger it. With Rumple it was hearing Emma’s name in the Pilot.
Also, what about the Godmothers weren’t there more then one how powerful were they
The episode Dreamy seems to imply that the job of FGM was a promotion from being a regular fairy and thus probably rare. But there are lots of nuns at the abbey (at least a decent amount). Some of them were probably FGM’s. We don’t know how powerful they were. They seem to have more magic than someone like Nova but they don’t compare to the BF.
